Beware of security nihilism when reacting to @Bitkey, the self-custody bitcoin wallet built by the team at Block. .
@tank raised a valid point when introducing his 2-of-2 seedless cloud backup scheme: 
Funny how 24-word seed phrases feel safer than 12.
(probably a cognitive bias 🧠)
Doubling the word count offers no real advantage. 🤷♂️
And it's twice as cumbersome to backup.
12 is enough, don't waste your time with 24.
It's been nearly a year since MicroStrategy announced their Lightning Platform with rewards and more. Haven't heard any updates since. Does anyone know if they're still working on it?
@BTC Map launched a leaderboard ranking countries by merchant adoption. Cool to see Brazil 🇧🇷 at the top!

Bitcoin is for enemies.
Bitcoin is for people like Nayib Bukele.
One day, our great-grandchildren will hear stories about the fiat era.
They'll study history through our memes.
They'll question why humanity tolerated central banks for so long.
They will own everything and be happy. 🥹

I was today years old when I learned that hovering over "Taproot" on @mempool shows this:
We need more opinionated Bitcoin products like TwentyTwo's Portal.
Don't overwhelm users with a million choices on how to use your product.
Enabling people to do everything diminishes the UX for everyone.
Most products should guide their users, not the other way around.
It's curious to see how hardware tradeoffs affect UX.
@Blockstream's Jade has one select button and a jog wheel, leading them to place the delete key ⌫ in an unusual (but surprisingly intuitive) spot in the recovery flow ↓ 
Would you trust a wallet that DOESN'T allow you to back up your seed phrase? There are no mnemonics on Bitkey, the wallet made by @jack's team 👇
Forget the $60k, the US dollar is close to an All-Time Low! Now ₿1661 can buy $1. It's getting early in Moscow! 🌅
everyone is fixated on the Number Going Up, but it's more fun to watch this Number Go Down 👇
@Bitcoin Atlantis has just launched its Fedimint federation in partnership with @Fedi. Pretty cool!
I especially like the feature that allows canceling payments sent to federation members.

hey @Egge, I'm loving my mattcrv@npub.cash, congrats!
is there a way I could set up to receive the ecash notes via DM? Or at least get notified via DM when there are notes to be claimed?
